Learned a couple things today. If you don't feel like mixing anything by hand, cause your drill/whip is on the job, and go for a bucket of mastic you've had for 3 months that you put a piece of plastic over the partially used mastic thinking it will last longer, the mastic will be infested with mold. Your wifes mixer is decent at mixing up plani patch but plani patch is a horrible tile setting material, (go figure) You actually can use a slide cutter to cut marble, and Firestone Walker Brewing makes an awesome/strong oatmeal stout.

So, Spreading the grout was fairly straighforward. The second I started spreading it though, I realized that pre-sealing the tile would have been a good idea. I'd put it on and it was nice and creamy but then when I would go to squeegy it off it was already pretty hard to scape the excess off with the float. Since this was a 3 sq ft sample board, were talking about a matter of seconds. I'll have to try again with some sealer.

I was trying to imagine I'd spread more like 5-10 sq ft so I let it sit for about 2 min and started washing. Again some sealer would probably help. It had already gotten pretty difficult to wash. I had to use a scrub pad, then follow up diagonally with a sponge. That didn't quite get it all off, so I had to just keep the areas still on the tile damp and scrub scrub with the sponge, right up to the edge of the tile being carefull not to touch the joints.

I wasn't really happy with the joints, they were about as full as I wanted them to be, but look kind of over washed, maybe you can tell from the pics. Definately going to try again but seal the marble first. As far as scratches, I'm pretty sure I didn't scratch the marble with the Fusion pro grout, This marble comes from lowes and they're nice enough to sell it pre-scratched, so Its hard to say.

While looking it over, some balsamic vinegarette dressing from my sub landed right on a grout joint. I just took the wet sponge and wiped it off, and so far theres no indication that it happened at all.

My experience with Fusion pro previously was pietre del nord 24x24 matte porcelain by emser, 1/16th joint. On that job I would spread about 10 sq ft at a time then It wiped right up, just a circular motion with the sponge, then diagonally, then follow up with a micro fiber rag an there was no haze left. course this floor is a little dirty in the pic but not from the grout.

Just tried fusion Pro last week at the JB forum event at Custom, looks pretty neat. Just wondering if it has one of the same properties that quartzlock claims in a bit of flexibility. One of quartzlock's demonstrations is that they will make a color channel kit size stick of quartzlock, let it cure and then show that it can bend a bit and twist without a problem. It's an interesting, nonscientific, illustration of its flexibility. And I just wanted to see if that was also a feature of fusion Pro grout. So if it hasn't been discussed before already, and somebody has a fusion grout job on going, why don't we see if it does the same type of thing by making up a sample stick, maybe set in a wax paper form and then showing the result. Pics please.
